OpenBSD Errata: January 14th, 2018 (libssl)

Errata patches for libssl have been released for OpenBSD 6.2.
An incorrect TLS extensions block is generated when no extensions are
present, which can result in handshake failures.
Binary updates for the amd64, i386, and arm64 platforms are available via
the syspatch utility. Source code patches can be found on the respective
errata page:
